Cannot read LDIF file when entry has no attributes #5
Description
I ran an ldapsearch against AD, to dump all entries my account has permission to see.
(I am using OpenLDAP ldapsearch client.)
I get back an LDIF file which includes some entries with no attributes:
dn: CN=NTDS Quotas,DC=ad,DC=example,DC=com
dn: CN=VolumeTable,CN=FileLinks,CN=System,DC=ad,DC=example,DC=com
dn: CN=IP Security,CN=System,DC=ad,DC=example,DC=com
etc...
I am not sure why. Maybe I have permission to see the entry exists but not read it?
Now, I try to parse this LDIF file with node-ldif. And it gets a syntax error when it gets to these entries because the attributes are missing.
I realise that per RFC2849 this is invalid syntax and node-ldif is just following the RFC:
ldif-attrval-record = dn-spec SEP 1*attrval-spec
But, given real world LDIF files seem to violate the spec in this way, it would be nice if node-ldif could be a bit more forgiving, even if just as an option...
As a workaround, I use this script to pre-process my LDIF file:
var input = require('fs').readFileSync("/dev/stdin", 'utf8');
input = input.replace(/\r\n/g, "\n");
input = input.replace(/\n /g, "");
input = input.replace(/\n#[^\n]*\n/g, "\n");
while (input.match(/\ndn:[^\n]*\n\n/))
input = input.replace(/\ndn:[^\n]*\n\n/g, "\n");
process.stdout.write(input);
but would be nice if there was an out-of-the-box solution.
